+# Samba monitoring with Netdata
+
+Monitors the performance metrics of Samba file sharing using `smbstatus` command-line tool.
+
+Executed commands:
+
+- `sudo -n smbstatus -P`
+
+## Requirements
+
+- `smbstatus` program
+- `sudo` program
+- `smbd` must be compiled with profiling enabled
+- `smbd` must be started either with the `-P 1` option or inside `smb.conf` using `smbd profiling level`
+
+The module uses `smbstatus`, which can only be executed by `root`. It uses
+`sudo` and assumes that it is configured such that the `netdata` user can execute `smbstatus` as root without a
+password.
+
+- Add to your `/etc/sudoers` file:
+
+`which smbstatus` shows the full path to the binary.
+
+```bash
+netdata ALL=(root)       NOPASSWD: /path/to/smbstatus
+```
+
+- Reset Netdata's systemd
+  unit [CapabilityBoundingSet](https://www.freedesktop.org/software/systemd/man/systemd.exec.html#Capabilities) (Linux
+  distributions with systemd)
+
+The default CapabilityBoundingSet doesn't allow using `sudo`, and is quite strict in general. Resetting is not optimal, but a next-best solution given the inability to execute `smbstatus` using `sudo`.
+
+
+As the `root` user, do the following:
+
+```cmd
+mkdir /etc/systemd/system/netdata.service.d
+echo -e '[Service]\nCapabilityBoundingSet=~' | tee /etc/systemd/system/netdata.service.d/unset-capability-bounding-set.conf
+systemctl daemon-reload
+systemctl restart netdata.service
+```
+
+## Charts
+
+1. **Syscall R/Ws** in kilobytes/s
+
+    - sendfile
+    - recvfile
+
+2. **Smb2 R/Ws** in kilobytes/s
+
+    - readout
+    - writein
+    - readin
+    - writeout
+
+3. **Smb2 Create/Close** in operations/s
+
+    - create
+    - close
+
+4. **Smb2 Info** in operations/s
+
+    - getinfo
+    - setinfo
+
+5. **Smb2 Find** in operations/s
+
+    - find
+
+6. **Smb2 Notify** in operations/s
+
+    - notify
+
+7. **Smb2 Lesser Ops** as counters
+
+    - tcon
+    - negprot
+    - tdis
+    - cancel
+    - logoff
+    - flush
+    - lock
+    - keepalive
+    - break
+    - sessetup
+
+## Enable the collector
+
+The `samba` collector is disabled by default. To enable it, use `edit-config` from the
+Netdata [config directory](/docs/configure/nodes.md), which is typically at `/etc/netdata`, to edit the `python.d.conf`
+file.
+
+```bash
+cd /etc/netdata   # Replace this path with your Netdata config directory, if different
+sudo ./edit-config python.d.conf
+```
+
+Change the value of the `samba` setting to `yes`. Save the file and restart the Netdata Agent
+with `sudo systemctl restart netdata`, or the appropriate method for your system.
+
+## Configuration
+
+Edit the `python.d/samba.conf` configuration file using `edit-config` from the
+Netdata [config directory](/docs/configure/nodes.md), which is typically at `/etc/netdata`.
+
+```bash
+cd /etc/netdata   # Replace this path with your Netdata config directory, if different
+sudo ./edit-config python.d/samba.conf
+```
